MACHINE FOR KNEADING DOUGH.

SPECIFICATION forming part of Letters Patent No. 551,714, dated December17', 1895. Application filed m 27,1895. Serial No. 557,358. (No model.)

150 all whom it may concern.-

Be it known that I, DANIEL W. BROMLEY, a citizen of the United States,residing at Lexington, in the county of Fayette and State of Kentucky,have invented new and useful Improvements in Machines for KneadingDough, of which the following is a specification.

This invention relates to dough-kneading machines, and has for itsobject to provide such a machine more especially designed for domesticuse and which shall be simple, durable and inexpensive in constructionand efficient in operation, and which may be readily taken apart forcleaning and similar purposes.

To these ends my invention consists in the novel features and in theconstruction, arrangement, or combination of parts herein afterdescribed and pointed out in the claim following the description, duereference being had to the accompanying drawings, forming a part of thisspecification, in which- Figure 1 is a front elevation of my improveddough-kneading machine. Fig. 2 is an end elevation thereof, and Fig. 3is a detail view of one of the journal-boxes.

In order that those skilled in the art may make and use the invention, Iwill describe the same in detail, referring to said drawings, wherein-The numeral 1 indicates the base upon which the machine is mounted andwhich may conveniently consist of a wooden board of any suitable ordesired size and shape. Adapted to be secured to the opposite ends ofthe base 1 are two bifurcated standards 2 and 3,each having perforatedbottom flanges 4, which are secured to said base by suitable screws 5.Said standards each consist of two parallel uprights 6 and 7, theadjacent faces of which are preferably planed smooth and are provided attheir lower ends with inwardly-proj ecting lugs 8,which form supportsfor the lower journal-boxes presently to be described. To one of saiduprights, as 6, of each of said standards is hinged one end of a yoke 9,the other end of which is provided with two downwardly-projectingparallel and perforated lugs 10, which are adapted to engage theopposite sides of and register with a perforated lug 11 formed on theupper end of the opposite upright 7, a pin 12 being adapted to be passedthrough said perforated lugs to fasten the yokes to the uprights 7. Athreaded'aperture is formed in each of the yokes 9, in which is fittedan adjusting-screw 13, the upper end of which is provided with ahand-wheel 14, while upon the lower end thereof is rigidly secured anannular shoulder 15, for the purpose presently made apparent.

Seated between each of the uprights 6 and 7 are two journal-boxes 16 and17, the lowermost boxes 16 each consisting of a cast metallic blockprovided at each side or edge with laterally-projecting flanges 18 thatengage the opposite sides of the uprights 6 and 7 and prevent anylateral movement of said box between the uprights, and upon the upperside of each of said boxes is formed a projecting boss 19, over which isadapted to be seated a coiled spring 20. The boxes 16 rest upon and aresupported by the shoulders 8 formed on the lower adjacent faces of theuprights 6 and 7, and said boxes are provided with coincident journal-bearings 21, in which are journaled the ends of a roll 22, oneend of which, as 23, projects through the bearing in the standard 3 andis provided with a detachable crank-handle 2i, by means of which saidroll may be rotated.

Resting upon the coiled springs 20 are two journal-boxes 17 similar inall respects to the journal-boxes 16 before described, excepting thatthe boxes 17 are provided upon both their upper and lower sides withbosses 25, the lowermost of which seat within the upper ends of thecoiled springs 20, while over the uppermost of said bosses are seatedsimilar coiled springs 26, and in the upper ends of said last-mentionedsprings project the lower ends of the adjusting-screws 13, the shoulders15 on the latter resting upon the upper ends of said springs. A roll 27is journaled in bearings in the boxes 17, said roll being similar in allrespects to the roll 22,before described, and said rolls at one end areprovided with intermeshing purchase-gear wheels 28, by means of whichthe motion of the driven roll 22 is communicated to the roll 27, causingthe two to rotate in unison.

From the base of the standard 3 depend two brackets 29, in which arefitted thumbscrews 30, by means of which the machine may be detachablysecured to a table or other suitable support.

The operation of my improved machine will be readily understood from theforegoing description.

The device having been secured to a table or the like in the mannerdescribed, the dough is introduced between the rolls, and the latterrotated by turning the crank 24. The dough is thus drawn between saidrolls and thereby rolled out and compressed, and by turning the adjlisting-screws 13 in the proper direction the rolls may be adjustedtoward or from one another to roll the dough out into any thicknessdesired. The coiled springs operate to maintain the rolls the desireddistance apart, while the springs 26 serve to cause said rolls toapproach each other with a yielding pressure through the medium of theadjusting-screws 13, whereby said upper roll may yield vertically inboth directions to perfectly accommodate itself to the dough beingoperated upon. By removing the pins 12 and throwing back the yokes 9 therolls, together with their journal-boxes, may be instantly removed fromthe machine and theroughly cleaned, and may, with equal facility anddespatch, be restored to their normal positions.

The machine constructed as above described is exceedingly simple,durable and efficient, the parts may be readily taken apart forcleaning, and the rolls may be readily adjusted to suit the character ofthe material to be operated upon.

Having described my invention, what I claim iS- A dough kneadingmachine, consisting 01": a base, two parallel uprights 6 and 7 securedto each end thereof, said uprights being provided at their upper endswith perforated lugs and provided upon their adjacent faces near theirlower ends with inwardly projecting lugs 8 to form supports forjournal-boxes 1G, yokes 9 hinged to one of said perforated lugs of eachpair of parallel uprights and provided at their opposite ends with twoparallel perforated lugs 10 that straddle the perforated lugs on theadjacent uprights and are detachably connected thereto by pins 12,vertically movable journal-boxes 16 and 17 arranged one above the otherbetween said uprights, the said boxes each consisting of a blockprovided upon its opposite sides with laterally projecting flanges 18that engage the opposite sides of said uprights, the boxes 16 eachhaving a boss 19 on its upper side, and the boxes 17 each having bosseson their upper and lower sides, rolls journaled in said boxes andprovided at one end with intermeshing purchase gears, set screws 13arranged in threaded apertures formed in the yokes 9 and provided neartheir lower ends with shoulders 15, coiled springs 20 arranged betweenthe journal boxes 16 and 17 and disposed over the bosses thereon andcoiled spring, 26 arranged between the journal boxes 17 and seated attheir lower ends over the bosses on the upper sides of the journal boxes17 and at their upper ends against the shoulders 15 on the set screws,substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of thesubscribing witnesses.

DANIEL WV. BROM LEY.
